启动docker registry

• $ docker run -d -p 5000:5000 --restart=always --name registry registry:2

docker会显示本地没有register:2

然后会从自己的仓库查找并且卸载这个镜像,然后启动.

检查成功启动的内容

• $ docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
efd78fe51f04        registry:2          "/entrypoint.sh /etc…"   4 minutes ago       Up 4 minutes        0.0.0.0:5000->5000/tcp   registry

拉取hello-world镜像

• $docker run hello-world

 

 打印如下日志

Hello from Docker!
This message shows that your installation appears to be working correctly.
 
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.
 
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

创建tag

• $ docker tag hello-world localhost:5000/helloworld:latest

尝试推送

•  $ docker push localhost:5000/helloworld

The push refers to repository [localhost:5000/helloworld]
af0b15c8625b: Pushed
latest: digest: sha256:92c7f9c92844bbbb5d0a101b22f7c2a7949e40f8ea90c8b3bc396879d95e899a size: 524

强制删除hello-world后,本地将不再有hello-world镜像

• $ docker rmi -f  镜像id号
• $ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
registry            2                   f32a97de94e1        2 weeks ago         25.8MB

尝试从本地私库拉取helloworld

• $ docker pull localhost:5000/helloworld

Using default tag: latest
latest: Pulling from helloworld

Status: Downloaded newer image for localhost:5000/helloworld:latest
 

停止registry

• $docker stop registry && docker rm -v registry

 

指定本地存储位置的registry

• docker run -d -p 5000:5000 --restart=always --name registry -v /opt/data:/var/lib/registry registry:2
